Rod retaining snap rod with enlarged retaining ring

Abstract

A modular belt having a first belt module and a second belt module intercalated and locked into position by a pivot rod having a head at one end and a retaining ring disposed in spaced apart relation relative to the head along the longitudinal axis.

1. An assembly for hingedly coupling parts of a conveyor, comprising a first conveyor part provided with a first row of hinge eyes spaced apart from one another with mutual interspaces with an end hinge eye located along a longitudinal edge of the conveyor part, with an end hinge hole which is somewhat out of alignment with respect to an adjacent hinge hole from the first row, further comprising a second conveyor part provided with a second row of hinge eyes which are also spaced apart from one another with mutual interspaces, such that the conveyor parts can cooperate in a coupled condition by receiving hinge eyes in corresponding interspaces, and a hinge pin provided with a central body part which extends, in coupled condition of the assembly, through hinge holes of the first row and of the second row, further provided with a thickened head which is able to pass the end hinge hole of the end hinge eye, but not the hinge hole of the next hinge eye in coupled condition, which thickened head is, in coupled condition, axially locked between the end hinge eye and the next hinge eye, while the thickened head bears a projection which reaches into the hinge hole of end hinge eye in coupled condition. 
   
   
     2. An assembly according to  claim 1 , wherein the first row comprises a sub-row with more centrally located hinge eyes with hinge holes aligned with respect to one another and an end hinge eye adjacent to the sub-row, with an enlarged hinge hole which is positioned somewhat out of alignment and with a locking surface adjacent to the hinge hole and positioned in alignment. 
   
   
     3. An assembly according to  claim 1 , wherein the hinge eyes of the hinge holes of the second row are provided with hinge holes aligned with respect to one another. 
   
   
     4. An assembly according to  claim 1 , wherein, with the aid of its thickened head, the hinge pin is axially locked between a locking surface of the end hinge eye on the one side and the next hinge eye on the other side. 
   
   
     5. An assembly according to  claim 1 , wherein the projection is substantially cylindrical. 
   
   
     6. An assembly according to  claim 1 , wherein the projection has substantially the same diameter as the body part of the pin. 
   
   
     7. An assembly according to  claim 1 , wherein the projection extends collinear with the central part of the pin. 
   
   
     8. An assembly according to  claim 1 , wherein the hinge pin is rotationally symmetrical. 
   
   
     9. An assembly according to  claim 1 , wherein the pin extends over the width of the conveyor. 
   
   
     10. An assembly according to  claim 1 , wherein the thickened head tapers from the projection towards the central part. 
   
   
     11. An assembly according to  claim 1 , wherein the cooperating conveyor parts form a substantially closed conveying surface. 
   
   
     12. An assembly according to  claim 1 , wherein the end hinge eye is partly reduced, so that the locking surface surrounds the hinge hole as a ring segment. 
   
   
     13. An assembly according to  claim 1 , wherein the end hinge eye is designed as a stop cam bearing on a locking surface and reaching outwards with respect to the body part, leaving a space corresponding with the hinge hole clear.
